LGN2D222MELC45

The LGN2D222MELC45 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 2.2 mF capacitance at a 200 V rating in a compact snap‑in radial can, and is built for sustained operation at elevated temperatures up to 105°C.

Engineered for reliable operation under continuous ripple stress, this part withstands rated ripple current for 3000 hours at 105°C and is RoHS compliant, making it suitable for designs that require long endurance and regulatory conformance.

Key Features

• Capacitance & Voltage: 2.2 mF capacitance with a 200 V rated voltage and ±20% tolerance, suitable for higher‑energy filtering and bulk storage in power circuits.
• High‑Temperature Endurance: Rated for operation from −40°C to +105°C and specified to withstand rated ripple current for 3000 hours at 105°C.
• Ripple Current Performance: Rated ripple current of 3.48 A at 120 Hz and 5.22 A at 100 kHz, supporting sustained AC ripple handling in demanding power applications.
• Snap‑In Radial Can Package: Snap‑in terminal, radial can package with a compact footprint (L: 4.5 × D: 3.5 cm), enabling robust board mounting and simplified assembly for through‑hole designs.
• Endurance & Shelf Life: Endurance criteria include capacitance change within ±20% and retention of leakage/tan δ performance after 3000 hours at 105°C; shelf life recovery procedures are defined in the datasheet.
• Polarized Design: Polarized capacitor intended for DC applications where polarity is managed by the circuit design.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• General‑purpose power circuits — Bulk energy storage and smoothing in DC power supplies where a 200 V, 2.2 mF polarized capacitor is required.
• Power filtering and ripple suppression — Use where sustained ripple handling at elevated temperatures is needed, supported by specified ripple currents at 120 Hz and 100 kHz.
• Industrial and commercial equipment — Applications that require long endurance at up to 105°C and RoHS conformity.

Unique Advantages

• Long-term high‑temperature endurance: Specified to withstand rated ripple current for 3000 hours at 105°C, reducing the need for frequent replacement in high‑temperature environments.
• Measured ripple capability: Explicit ripple current ratings at both low and high frequencies (3.48 A at 120 Hz; 5.22 A at 100 kHz) let designers size for real operating conditions.
• Compact snap‑in form factor: Snap‑in radial can and a smaller case rank than comparable series, facilitating secure board mounting and space‑efficient layouts.
• Clear performance limits: Endurance and shelf life criteria (capacitance, tan δ, leakage) are defined in the datasheet, enabling predictable lifetime planning.
• RoHS compliant: Meets directive requirements for restricted substances, simplifying regulatory considerations for product assemblies.
